"He took a thin roll of blue cloth from his sleeve.¶ This contrivance was one of Tao Gan's many ingenious inventions. When unrolled, it proved to be a roughly sewn bag made out of the blue cloth that people ordinarily use for wrapping up the bundles they carry. It had a square shape, but all kinds of queer folds and spare corners had been sewn in it. By fitting together, in various combinations, the dozen thin bamboo staves inside, Tao Gan could make this bag assume all kinds of shapes-- from the square bundle containing laundry to the oblong package full of books. In his varied career this contraption had proven especially useful to him.¶ Tao Gan adjusted the bamboo staves inside in such a way that the bundle seemed to contain carpenter's tools. His transformation was completed in a few moments and soon he was walking down the pathway, his shoulders bent a little as if the bundle he was carrying under his arm was quite heavy."
